Smithsonian / USGS Weekly Volcanic Activity Report. The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program.
Updated by 2300 UTC every Wednesday, notices of volcanic activity posted on these pages are preliminary and subject to change as events are studied in more detail. This is not a comprehensive list of all of Earth's volcanoes erupting during the week, but rather a summary of activity at volcanoes that meet criteria discussed in detail in the "Criteria and Disclaimers" section. Carefully reviewed, detailed reports on various volcanoes are published monthly in the Bulletin of the Global Volcanism Network. Copahue | Central Chile-Argentina border | 37.856°S, 71.183°W | Elevation 2953 m On 4 April OVDAS-SERNAGEOMIN reported that activity at Copahue continued to fluctuate at an elevated level however did not indicate an impending eruption.

Honshu earthquake tore gash in the Earth 150 miles long, 50 miles wide. March 11, 2011 – JAPAN - A massive earthquake that struck off the coast of Japan Friday was the strongest quake in the area in nearly 1,200 years.
David Applegate, a senior science adviser for earthquake and geologic hazards for the U.S. Geological Survey, said the 8.9-magnitude quake ruptured a patch of the earth’s crust 150 miles long and 50 miles across. He said the earthquake, which also spawned a massive tsunami that hit Japan before racing across the Pacific Ocean to Hawaii and the West Coast of the United States, likely caused tens of billions of dollars in structural damage in Japan. Laura K. Furgione, deputy director for the National Weather Service, said the tsunami first hit Hawaii early Friday morning. March 11 Japan earthquake powerful enough to shift Earth's axis. Many media are reporting today that the 8.9-magnitude earthquake in Japan on March 11, 2011 might have shifted Earth’s axis.
Some experts say 8 centimeters. Others say 10 centimeters. EarthSky is checking with its scientists/sources and will record an interview on this subject in the coming week, as more details become known. Earth’s axis of rotation is tilted at an angle of 23.5 degrees relative to the orbital plane at which Earth travels around the sun. This tilt causes our four seasons. Japan Quake May Have Shortened Earth Days, Moved Axis. Japan Quake May Have Shortened Earth Days, Moved Axis The March 11, magnitude 9.0 earthquake in Japan may have shortened the length of each Earth day and shifted its axis.
But don't worry—you won't notice the difference. Using a United States Geological Survey estimate for how the fault responsible for the earthquake slipped, research scientist Richard Gross of NASA's Jet Propulsion Laboratory, Pasadena, Calif., applied a complex model to perform a preliminary theoretical calculation of how the Japan earthquake—the fifth largest since 1900—affected Earth's rotation. Quake moved Japan coast 8 feet, shifted Earth's axis. Images released by NASA show Japan's northeast coast before, left, and after flooding from the quake-induced tsunami.
Friday's powerful earthquake appears to have moved the main island of Japan by 8 feet Report: The 8.9-magnitude earthquake shifted the Earth on its axis by 4 inchesThe quake triggered more than 160 aftershocks in the first 24 hours Similar strength to the 2004 quake and tsunami that killed more than 200,000 people (CNN) -- The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis.
"At this point, we know that one GPS station moved (8 feet), and we have seen a map from GSI (Geospatial Information Authority) in Japan showing the pattern of shift over a large area is consistent with about that much shift of the land mass," said Kenneth Hudnut, a geophysicist with the U.S. Geological Survey (USGS).

Earth Axis Tilt Experiment. ) with some gravitational variation experiments to determine the rate at which the earth's polar axis is tilting.
I have reason to believe that not only the north magnetic pole of Earth but also the axis of spin are beginning to undergo some dramatic changes. As you may have heard I am working on Part 2 of my gravitational research paper. As part of the research for that paper I devised some simple tests to monitor changes in the Earth's gravitational field between our northern and southern hemispheres. However, in the last few days our test results are starting to show what appears to be an alarming change in the Earth's gravitational field. As I was getting ready to publish this paper on our website, I received some disturbing test results from a fellow research assistant in New Zealand.
